The pfSense factory version is the version that is preinstalled
on units purchased from Netgate. The factory image is optimally tuned for
our hardware and contains some features that cannot be found elsewhere,
such as the AWS VPN Wizard.

After a minute the pfSense loader menu will be displayed that contains
options to Boot Multi User, Boot Single User, Escape to loader
prompt, Reboot, select a non-default kernel or configure boot options.
Either allow the menu to timeout and boot on its own, or press 1 to boot
normally. The factory images of pfSense already have appropriate console port
options.

The installer will automatically launch once the boot process completes and
offer the choice of a Quick/Easy Install, Custom Install, and several
other options. Select Quick/Easy Install and press Enter. Another
screen will prompt for confirmation. Select OK and press Enter to
continue.

pfSense will be installed to the first available disk in the system. If the
system contains an mSATA disk, it will be chosen. Otherwise, the onboard eMMC
will be used. It will take a couple of minutes to copy all of the files to
the target disk. When the files have finished being copied, the installer
will prompt to select either the Embedded Kernel or Standard Kernel.
Select the Embedded Kernel and press Enter.

If you are on the factory version, the installer will then prompt to choose
the type of system being installed, which pre-configures device-specific
defaults. Choose the option that exactly matches the unit being reinstalled.
If the model is unknown, check the sticker on the bottom of the unit.

The installer will then prompt to Reboot the system. Select Reboot
and press Enter. The system will reboot.

Remove the USB drive from the USB port. pfSense will restart automatically.
If the USB drive remains attached, the system will boot into the installer
again because by default the system firmware is configured so that a device
plugged into the USB port will be booted with a higher priority.
